Influence range of loess landslide in the Southern Jingyang Plateau based on numerical simulation and mathematical statistics

open access: closedArabian Journal of Geosciences, 2021
The property losses and human casualties caused by large-scale loess landslides are very serious, so it is of great practical significance to study influence ranges of the loess landslides. Take Southern Jingyang Plateau (SJP) as an example. The influence range of the loess landslide in the SJP is determined by the change of the tableland edge and the ...

A mathematical investigation of the air-ground temperature relationship in permafrost regions on the Tibetan Plateau

open access: closedGeoderma, 2017
Abstract Air and soil temperatures are important factors that contribute to hydro-thermal processes and ecosystem dynamics in permafrost regions. However, there is little research regarding soil thermal dynamics during freeze-thaw processes in permafrost regions with thermal orbits on the Tibetan Plateau.

A mathematical model of the relationship between cerebral blood volume and intracranial pressure changes: The generation of plateau waves

open access: closedAnnals of Biomedical Engineering, 1991
The relationship between intracranial pressure (ICP), cerebral blood volume (CBV), cerebrospinal fluid dynamics, and the action of cerebral blood-flow (CBF) regulatory mechanisms is examined in this work with the help of an original mathematical model.

Mathematical model for the plateau region of P–C-isotherms of hydrogen-absorbing alloys using hydrogen reaction kinetics

open access: closedComputational Materials Science, 2002
Abstract A theoretical treatment is presented to account for the two-phase (α–β) region of pressure-composition (P–C) isotherms of hydrogen-absorbing alloys, i.e., the dependence of equilibrium pressure on the hydrogen concentration in hydrogen-absorbing alloys at different temperatures.

Does watershed size affect simple mathematical relationships between flow velocity and discharge rate at watershed outlets on the Loess Plateau of China

open access: closedJournal of Hydrology, 2012
Summary An empirical power function model of V  =  kQ m has been used worldwide to describe the relationship between flow velocity ( V , m s −1 ) and discharge rate ( Q , m 3  s −1 ) for rill and open channel flows. However, it has seldom been applied to watershed outlet channels taking into account the impacts of watershed size.

Effects of mathematics learning corner on preschoolers' mathematical skills in Jos South, Plateau

Journal of Educational Foundations, 2019
This study set out to examine the effect that mathematics learning corner has on nursery pupils' mathematical skills in Jos South, Plateau state. The research design was a quasi-experimental research design. The sample of the study comprised of 48 pupils in two intact groups who were randomly assigned to experimental and control groups.
